"It's a pity, it's a pity."

After coming to this fact, Qing Xishii's face was full of regret, it is true that with the joint efforts of her and Li Yalin, she did find an antidote to cure the zombie virus, but this antidote was too precious, and there was no possibility of mass production at all.

There is no way, Li Yalin can't bleed all the time, and it is absolutely impossible to save the world with this.

"There's nothing to worry about, that's enough."

is different from the regretful Qingxian Shizi, Li Yalin is very calm, because he has never considered saving the world from beginning to end, and it is enough to protect the girls around him.

As for what the world will eventually become, what does that have to do with him?

He is not the savior, and the great cause of saving the world should be left to the saviors to complete.

"You're so calm, do you know what will happen to you if I spread the news that your blood can cure the virus?"

Seeing that Li Yalin was so calm, Qing Xianzi suddenly raised his eyebrows, and he didn't know if it was because of his indifferent attitude.

"If you do, the survivors will probably rush to this school in droves, and they will arrest me and use me as a blood-making machine."

Shrugged his shoulders towards Qing Xianzi, of course Li Yalin knew the consequences of doing that, his blood was Tang monk meat, although it could not make people immortal, but it was a life-saving medicine.

Once this secret is discovered, the Patrol Hill Academy will be easily destroyed.

"You're not afraid that I'll really spread the news?"

Qing Xian Shiiko found that he couldn't understand the man in front of him...... Or a boy, he clearly knows his importance, and he should see through the dark side of human nature, so why can he be so calm?

Is he so confident?

Is he so confident that he won't reveal the news?

"If the Patrol Hill Academy is captured, I will become a blood-making machine, but you will all die."

Faced with Qing Xianzi's doubts, Li Yalin shook his head slightly.

Believe in the green attack spine?

No, he just believes in human nature.

Qing Shiiko is a smart person, she knows the consequences of doing so, and the emergence of a life-saving medicine will not really save humanity, but will accelerate the speed of human demise.

And once there is a conflict, these girls from the Patrol Hill Academy will inevitably be the first targets to be eliminated, including Qingyun Shiiko.

So she won't reveal this secret, both for the sake of this safe place to live, and for herself.

Li Yalin still has this confidence.

"Tsk...... It's a really annoying guy, eat more blood-replenishing food for a while, and I'll arrange blood transfusions from tomorrow onwards. ”

Seeing that she hadn't been able to scare Li Yalin, Qing Xianzi pouted her lips very unpleasantly, she really couldn't understand, she was just a little guy from a high school student, why did she come so calmly?

didn't scare anyone, and Qing Xianzi didn't plan to continue talking nonsense, she knew very well what she had to do, and she also knew how much Li Yalin cared about those little girls.

She knew that she was brought by Li Yalin to study the zombie virus in order to save these girls, especially after learning that his blood could be immune to the zombie virus, she was even more sure of this.

Although he is not cute at all in front of him, and he does not have the youth and impulsiveness that a young boy of this age should have, he has to admit that he is a good man.

Well, even if you are a little older, you can definitely be called a good man.

It's not a bad feeling.

Since it's his wish, help him accomplish it!

According to Qing Xian's research, if you want to have a physique that is immune to the zombie virus, you need to inject at least ten milliliters of blood, so at her suggestion, Li Yalin drew four hundred milliliters of blood at one time.

Except for the one left for injection, the rest of the blood is sealed and refrigerated in case of emergency.

After all, injecting blood does not mean that it is foolproof, and it is very necessary to have more spare blood.

Regarding this point, Li Yalin agrees very much, anyway, as long as it does not exceed 400 milliliters, it will not damage the body, so it should be regarded as a free blood donation, with his current physique, he can replenish the lost blood in a few days.

Soon, everyone at Xunzhigaoka College learned the good news that Mr. Qing Xianshiiko, a virus expert from St. Isidore University, had successfully developed a virus immunity agent, which was verified by Li Yalin.

Although it could not be mass-produced, it could be provided to every member of the Patrol Hill Academy, and this news was undoubtedly a huge surprise.

Yes, everyone thought that the so-called virus immunity agent was developed by Qingxian Spine, although they were puzzled by the bright red color, but they didn't think about the blood.

This is the result of Li Yalin and Qing Xizhizi discussing in advance, and I will not tell everyone the truth for the time being.

Li Yalin didn't feel that he had contributed much, and he didn't plan to get everyone's gratitude for it, not to mention that once everyone knew the truth, if they accidentally revealed it one day, they would definitely cause trouble.

So that's the best outcome.

Now the Patrol Hill Academy has undergone great changes with the joint efforts of everyone, and the outer wall has been transformed very strongly, whether it is zombies or humans, don't want to break through easily.

On campus, the division of labor is also very clear, and a group of university team members led by Hikari Crystal and Exit Kiriko have successfully cultivated several vegetable fields on the playground, and I believe that it will not be long before everyone can eat more fresh vegetables.

And the girls in the high school group, they have shouldered the heavy responsibility of guarding the campus and going out to explore and search, which can be said to be an important force to protect everyone.

As long as they are around, the Patrol Hill Academy is an impenetrable fortress.

As for the group of loli in the elementary school group, given that they are still young, they should continue their education, so they still have to be taken care of by Sakura-sensei and Kamiyama-sensei.

Of course, they occasionally come to the vegetable field to help out and do what they can.

In addition, the library of Legakawa Principle is here, and many things that everyone doesn't know can be consulted with her, and if you get sick, you can also help treat Qing Shige.

Before you know it, Patrol Hill College has been built into the perfect place to live, and compared to St. Isidore University, it is simply like a paradise!

I really didn't expect that I would do it to this extent.

I didn't expect that this was actually the Garden of Eden, a girl recognized by the system.

Yes, with the improvement of the Patrol Hill Academy, Li Yalin's task was also completed, seeking living space for the girls, and he really did it!
